Nigerian English (NigE) is a second language (L2) variety of English that has been domesticated, acculturated and indigenised within the Nigerian socio-cultural and linguistic contexts (Adegbija, 2004). Based on Schneider's (2007) Dynamic Model of the Development of New Englishes, scholars have shown that NigE is currently at the late stage of nativisation (stage 3) and is on the verge of entering the stage of endornormative stabilisation (stage 4) (see Gut, 2012; Collins, 2020). Nativisation, which typically begins with the declaration of independence, is a very active and important stage in which there are large-scale linguistic changes, especially during a time when English is usually the only official language (see Schneider, 2007). Although previous studies have investigated the historical development of English in Nigeria (see Taiwo, 2009), there are limited studies on the particular linguistic features that have changed over time, especially from the time Nigeria gained independence. It is very likely that the rapid increase in the number of universities and other educational institutions managed by Nigerians from independence, as opposed to previous management by Britons, would have affected the variety of English spoken in Nigeria and culminated in the development of NigE today.

尼日利亚英语 (NigE) 是英语的第二语言 (L2) 变体，已在尼日利亚社会文化和语言环境中被驯化、文化化和本土化 (Adegbija, 2004)。基于 Schneider（2007）的“新英语发展动态模型”，学者们表明，NigE 目前处于本土化后期（阶段 3），即将进入规范化稳定阶段（阶段 4）（见肠道，2012 年；柯林斯，2020 年）。本土化通常始于宣布独立，是一个非常活跃且重要的阶段，在此阶段会发生大规模的语言变化，尤其是在英语通常是唯一官方语言的时期（见 Schneider，2007）。尽管以前的研究已经调查了尼日利亚英语的历史发展（见 Taiwo，2009 年），关于随时间变化的特定语言特征的研究有限，特别是从尼日利亚获得独立时起。与以前由英国人管理的情况相比，尼日利亚人从独立后管理的大学和其他教育机构的数量迅速增加，这很可能会影响尼日利亚使用英语的多样性，并最终导致今天 NigE 的发展。
